把错误日志也贴一下吧

看下你的 bootargs

然后检查你的根文件系统有没有 /dev/console 文件.

是不是要求、inittab中的那句，必须与sun8i.h中的那句保持一致？

我刷新\v3s-rtl8723bs\的u-boot-sunxi-with-spl.bin和rootfs.tar.gz，依然不行。。。。。有看到rootfs内有console(解压看的）

没有。这两个包是官方的，是独立包。

这个方法行不通。mmcblk0p2是读SD卡MMC卡等这种设备的。而且这个上面也说明了它是读二区。这个节点不能用在Flash上。（贴了Log）

可能因为 /dev/ram0 对应的 ramdisk 根文件系统有正常的 /dev/console.

如果选其他rootfs (/dev/mtdblockX) 编译内核的时候, 要记得把 ramdisk 勾选去掉.
